Fitech issues

Checked the slop no issue there. So I went about halfway back to where I started set base time at 10 deg. Fired up and tried to idle. Got the timing light out started again and shot the balancer. Showing about 6deg on the balancer. But I would get an erratic spark here and there. Late spark about every 5-10 blinks about 10-15 deg late. Checked controller codes and came up with the rpm noise code.

Should I bite the bullet and buy the real deal MSD? Junk the 50$ msd knockoff or start shielding wires? Only wires that need shielding are the 2 distributor wires correct. I don’t really see what they would need shielding from as the wires come out of the dristributor and go under the intake runners and come up to the throttle body no where near the ignition wires.

Buy the MSD adjustable rotor and read this article.
